running Oracle dbstart in the init script

[Sanjay Gupta <sanjay@xxxxxxxxxxxxx>]

Hi !!

I hace installed Oracle on rhl 6.2 box
It is working perfectly fine. Now I wanted to start my instance
automatically
using rc init scripts. But some how it is not working
I am enclosing the script which I am using. When I run it it says
[Failed]
please guide.

With best wishes
Sanjay Gupta
